FEED GAUGE.

Application filed September 12, 1924. Serial No. 737,305.

This invention relates to a feed gauge and is more particularly adaptedfor use in `connection With perforating machines.

One of the objectsof the present invention is to provide an improvedfeed gauge, which is simple in construction and efficient in operation.

A further object of the invention isto provide an adjustable feed gaugewhich can be quickly and easily changed to meet various reqnirements.

A still further object of the invention is to provide a device of theclass described, which will operate with the least possible effort onthe part of the operator.

These and other objects are accomplished by providing a construction andarrangement of the variousparts inthe manner hereinafter described, andparticularly pointed out in the appended claims.

Referring to the drawings- Fig. 1 is a top plan view of my `improvedfeed-gauge;

Fig. 2 is a cross sectional View taken on the lines 2-2 of Fig. 1;

Fig. 3 is an enlarged fragmentary cross sectional view taken on thelines 3--3 of Fig. 1.

Fig. 4 is an enlarged fragmentary top plan view of the guiding member orcarriage; and

Fig. 5 is a cross sectional and side elevational view of theconstruction shown in Fig. Li.

The invention, in the present instance, `is directed to a feed gauge,which is particularly adapted for use in connection with theintermittent feedingof pre-determined lengths of paper or the like to amachine such, for instance, as a perforating machine, so that the paperso :fed is perforated at predetermined :inter tals.

The present invention is"particularly useful in connection with theperforation of bank checks and the like where the checks are a1.'-ranged o n large sheets of paper, and a rc perforated from each othersothat each check may be readily torn from the remaining checks onv thesheet.

In carrying out the present invention, I have shown my improved feedgauge being mounted on a base 10, `which is preferably made of Wood forthe purpose of lightness, but which might Well be made of any material,such, for instance.` as aluminum or other metals. "The base issubstantially square in outline7 and is provided, on one side thereof,with a recess 11 to accommodate the operator. Positioned on the oppositesides of the base l() adjacent the outer edges thereof and extendinglongitudinally With respect thereto are flat metal strips 12, which aresecured thereto by Wood screws 13. Extending along the metal strips 12'and secured thereto by means of rivets 14 and slightly overhanging theinner edges thereof are longitudinal tracks 15.

- Positioned on the opposite sides of the feed gauge and secured to themetal strips 12 by means of brackets 16- are two longitudinallyextending bars 17. These bars 17 are square in cross-section, and aredetachably secured in horizontally disposed apertures 18 in the brackets16 by means of set screws 19. Mounted on the square bars 17 are aplurality of stops 20, which are adapted to be adjusted `longitudinallyofthe bar. These stops are adapted to be locked in predeterminedpositions of adjustmentby set screws 21, which extend through thesestops in a manner to clamp the stops to the bar 17.

Mounted on the tracks by means of rollers is a carriage or guidingmember 22. The carriage or guiding member comprises a transverselyextending sheet supporting` member 23 having its forward edge beveled,as shown at 24. The carriage is mounted on the tracks in such a mannerso that the sheet supporting member is slightly positioned above thebase 10 in order to permit the same to be freely moved back and forth inthe tracks Without engaging the same. The sheet supporting member 23 hassecured on the onter ends thereof by means of screws (not shown) rollerbrackets 25. The outer ends of the roller brackets 25 are provided withhorizontally rotating rollers 26, which are adapted `to engage the inneredges of the tracks 15.

These rollers 26 are spaced a consiiilerable distance apart so as toproperly guide the carriage 1n a line substantially parallel to thetrack. One of the roller brackets '25 is provided With two verticallyrotatable rollers 27,

which are positionedadjacent the rollers 26, andare adapted to engagethe uppersurface of oneof the tracks`15, While the other roller brackets25 is provided with a single` vertically rotatable roller 28, which ispositioned adjacent the forward roller 26, and adapted to engage thenpp'er surfaceof the other track 15.

The object of providing the two rollers 27 on one side thereof,` andtheA singleroller 28 on the other side thereof, is to permit thecarriage to operate in the event the base, which in the presentinvention is made of wood.v warps. Infother words, in the event the basel0 should warp and if two rollers were provided on the opposite sidesthereof, the device would become inoperative, because the carriage wouldbind by reason of this warping.

The roller brackets are provided, on the outer sides thereof, withsockets 29, which are adapted to receive and have reciprocally mountedtherein pawls 30. The pawls 3() are normally pressed outwardly byextension springs 3l engaging shoulder 3&3 of the pawl 3() at one endthereof, and engaging the base of the sockets 29 at the other endthereof. The pawls 30 are provided with inwardly projecting stemportions 33, which have vertical apertures, as shown at 3l. The pawls3() are provided with bevelled portions, shown at 35, which are adaptedto engage bevelled portions 3G of the stops 2() when the carriage ismoved forwardly, and when the farriage is moved rearwardly vthe rearwardfaces 37 of the pavvls 30 are adapted to engage the forward faces 38 ofthe stops 20. The pawls `are actuated or withdrawn from their outermostposition by hand ope ating levers 39', which are mounted on cranks 39pivoted by means of a shoulder screw 4l to a reinforcing bar 4t2, which,in turn, is secured to the sheet supporting` member 23 in any well knownmanner.

In order to properly position the paper so that the edges thereof willbe parallel with the track or the movement of the carriage, I

have provided an aligning bar 4l which is adjustly secured to the member23 by means of screws 42. The levers 39 are each connected to the pawls30 by means of a connecting' rod 43. In order to prevent my carriage 22from being' entirely disengaged from the track in its movement, I haveprovided stops 44 secured to the opposite ends of the strips 12, asclearly shown in Figs. 1 and 2.

In the operation of the above described device, it will, of course, beunderstood that the stops 2() are positioned at desired intervals, or atthe intervals at which it is desired to perforate the paper, and securedin these positions by set screws or bolts 2l. lhen this is done thepaper to be perforated is positioned on the sheet or paper carrying`member 23, with the edges thereof enpaging, the front edges of the barill and held thereon by the hand of the operator. lVhen in this positionthe carriage is held so that the faces 37 of the pawls 3() engage thefaces 38 of the first stops 20. Then in this position the perforatingmachine is then actuated by the control lever of the operator. After thefirst perforations havebeen made in the paper the carriage is pushedforwardly 'by the operator past the next forward adjacent stops. In thepassing of thenext stops forwardly it will be noted that the beveledsurfaces of the pawls 30 engage the beveled surfaces 36 of the stops 2Oand cause these pawls to snap after passing these stops. As soon as thepawls snap, or are forced to their outermost position, the carriage isthen drawn backwardly so that the faces 87 of the pawls 30 engage thefor yard faces 38 of the stops just previously passed, and then theperfor-ating' machine is again thrown into operation to perforate thenext set of pcrforations.

This operation is continued until the sheets have been completelyperforated, and then the carriage may be withdrawn lto its rearmostposition by actuating` the levers 39 inwardly, an d thereby drawing' thepawls 30 inwardly against the tension of their extension springs 3l,thereby permittingl the carriage 22 to be withdrawn to its rearmostposition,

From the above description it will, of course, be understood thatadditional stops 20 may be added if necessary, and that these stops maybe positioned along their respective bars l'i' in such a manner that anyinterval between the perforations may be had.

From the above it will be noted that I have provided a very simple andetlicient feed gauge, and one which may be adjusted to meet variousrequirements.

It will also be noted that I have provided a device which will insureaccurate and parallel perforations of the sheets of paper placed on thecarriage.

And furthermore, I have provided a device which will not bind, but, onthe contrary, will operate with great facility and ease.

While in the above specification I have described one embodiment whichmy invention may assume in practice, it will, of course. be understoodthat the same is capable of moditication, and that modification may beemployed without departing from the spirit and scope of my invention asexpressed in the following' claims.

What I claim as my invention and desire to secure by Letters Patent is:
